Original application filed July so, 1917, Serial No. 183,595. Divided and this application filed June is, 1919. Serial No. 304,648. I

To all whom it may concern Be it known that I, EUGENE SCHNEIDER, a citizen of the Republic of France, and a resident of Paris, France, have invented a new and useful Improvement in Removable Bogies for Trailers, Gun-Carriages, and other Apparatus, which invention is fully set forth in the following specification.

In my application Serial No. 183,595, filed July 30, 1917, for improvements in bogies for trailers, gun carriages and the like, of

which the present application is a division, I have described a bogie construction adapted to any desired carriage framing, such as a trailer or gun carriage, the variable number of bogies constituting as many elastic suspension devices.

The characteristic feature of the improved bogies is that the bogie axle is connected at its center by a ball and socket joint or a horizontal pin to a member constituting the lower abutment, and it may be also the guide, for an elastic suspension, the upper abutment of which is constituted by one of the essential elements of a screwjack or like device, which is pivotedtabout a vertical axis bymeans of the support of the other element of the screwjack or by the actual frame of the screwjack in the carriage framing.

This arrangement is such that, on operat ing the screw-jacks in one direction, the carriage framing may be lowered to rest on the ground in firing position and by continuing the operation the bogies may be lifted off the ground. By reversing the operation, the bogies may be lowered to the ground and by continuing the operation the framing may be lifted into traveling position off the ground. The bearing of the wheels on the ground is assured whatever the contour of the surface during travel.

In order that the invention may be more readily understood, reference is had to the accompanying drawings which Show one constructional form of the invention.

Figure 1 is a view partly in longitudinal vertical section and partly in side elevation showing a bogie embodying my improvements.

Fig. 2 is a view partly in transverse vertical section on, the line 22 of Fig. 1 and partly in front elevation, and

Fig. 3 is a view partly in plan and partly the screwjack nut, the nut G proper being formed in the rear of the bracket. A plate D is mounted on the axle B and is connected therewith through a loose joint such as a ball-and-socket joint B and serves as the lower abutment for a pair of flat suspension springs E which support the outer end of bracket G through a pivot G The upper and lower members of the pair of springs E are secured by straps H respectively to pivot Gr and to plate 1).. The free endsof the springs are separately connected by pins P. Four upright members G project from pivot Gr beyond axle B and serve as guides for the springs E, plate D and axle B The lower ends of these guides are held by a nut N.

Assuming that the parts of the screw-j ack bogie are in the position shown in Fig. 1 then by turning screw F in the proper direction the framing I may be lowered in respect to the bracket arm G to rest on the ground.

By continuing the rotation of the screw the bracket G rises till the nut N meets the lower side of the wheeled axle which is then lifted off the ground.

If desired, the wheeled axle may be disconnected from the screw-jack by removing nut N, thereby permitting guides to be lifted free from the axle B. The upper member of the pair of springs E at the same time Separates from pins P.

What is claimed is:

1. In a bogie for supporting a trailer, gun carriage or other vehicle, a wheeled axle, a vehicle frame and springs supporting said frame on said axle, a screw element revolubly supported on said frame, a vertically movable bracket arm having at its inner end threaded engagement with said screw element and at its outer end a pivot adapted to constitute the upper abutment for said springs, and a plate having a-loose connection with said axle and adapted to constitute a lower abutment for said springs.

2. In a bogie for supporting a trailer, gun

carriage or other vehicle, a wheeled axle, a vehicle frame and springs supporting said frame on said axle, a screw element revolubly supported on said frame, a vertically movable bracket arm having at its inner end threaded engagement with said screw element and at its outer end a pivot adapted to constitute the upper abutment for said spring and having depending members for receiving and guiding said axle and springs, and a plate having a loose connection with said axle and adapted to constitute the lower abutment of said springs.

23. In a bogie for supporting a trailer, gun carriage or other vehicle, a wheeled axle provided with a plate having a loose connection therewith, two sets of separable flat springs the lower set of whichis fast to said plate, a screw element revolubly mounted on said frame, a vertically movable bracket arm the inner end of which has threaded. engagement with said screw element, a pivot mounted in the outer end of said bracket arm and to which said upper set of springs is fast,-said pivot being providediwith depending guide members for receiving and guiding said springs and axle.

In testimony whereof I have signed this specification.
